To all whom it may concern; i

Be it known that I, CHARLES Tn'r'rENnoaN, a citizen of the United States, and residing at Cincinnati, Hamilton county, State of 0hio, have invented certain new and useful declare the following to be a clear, full, and exact description of theinvention, attention being called to the accompanying two sheets of drawings, with the reference characters marked thereon, which 'forms also a part of this speciicz-iltion. This invention relates to refrigerators and concerns improvements in the genera-l. construction thereof as 'Wellas of certain parts and their arrangementfvvhereby the manufacture of such structures is simpliied and their usefulness increased. ln the following specification and particularly pointed ont in the claims at the end thereof, will lne-found a full description of my invention, together with its parts and construction, which latter is also illustrated in which Figure 1, isa sectional elevation of such a refrigerator, the section being ta keu on a plane between front and back Walls. Fig. 2, is a vertical section taken at. right angles to the section shown in the preceding ligure. Fig. 3, .is a horizontal section taken onV line 3-3 of 1, and 2. Fig 4l, is a` top-view of the drip-receiver. Fig. 5, in a. View similar to Fig. 1, shows parts of my invention applied to a refrigerator modified as to its internal arrangement.

A, indicates provision spaces or chambers, the two opposite sides of \vhieh also back, bottom and top are all contained lin an integral structure as shown and formed. out of4 porcelain or clay which is burned and glazed, or other equivalent material maybe used: The front is open and maybe closed by`a door 10, supported in. the `front wall of the refrigerator. The sides ha.ve\integral ledges 11, for supporting shelves 12, which may be` of Wirework. Above the provision-chamber there is an ice-chamber B, which contains the ice, which is supported upon a rack C. 13 13, are the sides of this chamber, 14 is the back wall thereof, and 15 the top, all being covered with a lining 16, of zinc or galvanizedl Letters Patent. Patenten. nov. 24, isos.

ported in vthe front-wall of the frigerator and above door 10 therein.

The ice-rack is supported at opposite edges in channeled guide-Ways 18, attached opposite each other to the sides ot the ice-cham-Y ber. This permits the rack to be slid partly out as shown in dotted lines in Figs. 2, and

3, to facili-tate placing the ice. bars 19, composing the ice-rack are tilted as best shown in Fig. 1, to lessen their tendency to ont edge-wise into the melting ice. Aron nd these chambers A and B, there are spaces provided which are closed-outwardly by in- Vtermediate Walls, preferably of boards, 21 being the wall below the bottom of chamber A, 22, 22, and 23, being those opposite sides The parallel and backs of chambers Aand B, and 24C, the

outer inl'osingwalls of the refrigerator', this being the bottom 27, the sides 28 28, and the bac-k 29. Sides 28, 28, and back 29, are lined on their inside with a layer of mineral-Wool 31, which is confined in position by paper coverings 32, and held by cleats 33 tacked in place. This mineral-Wool lining is l1mited in thickness so as not to` close np the air-spaces 26, in which it is contained.

Circulation Within -the refrigerator is induced by an opening 34 in top 35, of chain ber A, through ,which the cold air passes down. The Warmer air displaced thereby passes outthrough openings 236, 36, in sides 37, 37, and close under top From here it passes upwardly through fines 38, 38, iormed between the sides 13, 13, of the iceehamber and the boards 22, Y them. Sides 13, 13, terminate below the top of' the ice-chamber, thus rendering the upper ends of the fines open towards this cha-n1- ber, `and permitting the air passed up from below to reenter the circulation." At their lower ends these fines are closed against the cork-space 25', below, by strips 39, which in combination with ledges on the outside of sides 87, serve also to eenterchamber A..

of this" chamber, there is a door 17, sup-ll :l in position.

22, oppositey lower edges oir' the Wells or" iccfchember B,

meet this ridge, end lining 16 posses over' the joint to prevent leakage thereet es shown Ain Figs. and 2. `inother ridge 42, is provided around opening 34 in top 35, to prevent any Water from entering provisioncheinher A, below. The dripsivatcr passes out through on opening 4-3, and is carried onf in. the usuel manner through o Westepipe 44, the upper end oi' which connects to a. nipple on the underside of tcp 35, and belovf opening` 43. This nipple forms en integral projection. on the underside 'of top 35. 'To prevent Water from the ice dripping'directly through opening 34 into chenier A, I provide e shed 46 on the underside oi` the-ice-raclz and of an ores, suilicient to cover the opening below (see Fig. 3).. low this shed, but spaced therefrom, there is another shed 47, which cntches the condensetion forming on the underside of the upper shed and also directs the seine into receiver Ai-O. These two sheds are secured by lugs 4S, and attached thereby to seine y of the rods 19, which form ports of' ice-rack C. lit Will be seen that l dispense .with the usual drip-pon, sincetop 35, of provisioncheinoer A, constitutes the seme. IThe space thus set free nioy be utilized for other purposes or for reducing the dimensions ofthe refrigerator. I utilize this space for storage of bottles, canned goods, cto, which are thus cooled by the drip-Water as shown.

lThe front-edge of ice-reels C, is curved in e manner es liest shown in Fig. 3, and so os to recede et the front corners, thereby setting; thespace free thereat cl3-ove the drip-water receiver sind permitting larger sized hotties like mineral Water bottles to occupy this spa/ce while resting in the dripreceiver. ln Fig. 5, shov,T the eetures oi such e drip' receiver formed on the top of s, previsionn chamben also as en licsble tore refrie'erstor in which provision-chamber end circulation El) ere diiierently arranged.

'In all forms, the Aopeningl provided in front-:frame 4,9, for the door of the rovision-chsnih'er is arranged to be larger tnen 'the open side of the provision-chamber boch'.

t5 of it, so that the inner edge of seid opening.,

or gfemh 5i does not projectebeve the inner front edge of the Wells oi' seidchemher bach of frame 4Q. (bserve Fig. 2)., This permits this chamber end the Wells or it to he cleanly and completely wiped out, since the edge of the jeinh does not form en interior? ing projection, hehind which impurmes nightlodge and occninuiete unseen. Senitsrily considered, this is en importent factor,

since by this construction projections, formfcommei ing inaccessible corners, nre avoided und eiective cleaning is mede possible.
